Hainan crane manufacturers and the origin of driving - Hainan Taishan Hoisting Machinery Co., Ltd.
When did the crane first appear, and what was its original form? Many people often mention "driving," but this "driving" is not a type of movement (xing), but rather a form of lifting machinery. Below, let's ask port crane experts to explain the origins of cranes and their development over time.
In fact, the earliest prototype of a boom-type crane can be traced back to the simple water-lifting devices used in ancient China for irrigation. These early tools laid the foundation for more complex lifting mechanisms. In the 14th century, human and animal-powered rotating boom cranes began to appear in Western Europe. By the early 19th century, bridge cranes emerged, and key components such as shafts, gears, and spreaders started being made from metal materials, with hydraulic systems gradually becoming common.
By the late 19th century, steam-powered cranes began to replace hydraulic ones, marking a major technological leap. Then, in the 1920s, with the rapid development of the electrical and internal combustion engine industries, cranes powered by electric motors or diesel engines became widely adopted and established a solid foundation for modern crane technology.
So, what exactly is a bridge crane? It is a lifting device commonly used in workshops, warehouses, and storage yards to lift heavy materials. Its structure resembles a bridge, as it is supported by tall concrete pillars or metal frames on both ends. The bridge runs along rails installed on the elevated sides, allowing efficient use of the space underneath without interference from ground-level equipment. This makes it the most widely used and numerous type of lifting equipment in industrial settings. Port cranes play a crucial role in professional lifting and transportation operations—welcome to learn more about them.
What defines a foundry crane? It is specifically designed for pouring molten iron into blast furnaces, steelmaking furnaces, and for lifting molten steel into continuous casting machines or steel ingot molds. The main trolley carries the ladle, while the auxiliary car performs tasks like tilting the ladle. To enhance the range of the auxiliary hook and better support the steelmaking process, the main and auxiliary hooks are placed on separate trolleys that run on their own tracks. Common structural types include four-beam four-track and four-beam six-track configurations, offering flexibility and efficiency in high-temperature environments.
